Extensive Compatibility, Ready-to-Use: Fits 10mm, 12mm, 14mm, and 18mm spark plug holes, covering most gasoline engines (cars, trucks, ATVs, motorcycles, lawnmowers, etc.). Includes full set of adapters – no extra purchases needed. Works out of the box
Precise Leakage Source Identification: Professional dual gauges (0-100 PSI / 0-700 kPa) clearly display leakage rates. Not only detects cylinder leakage volume but also pinpoints failure sources (worn piston rings, leaking valves, blown head gaskets)
Professional Dual-Gauge Diagnosis & Stable Pressure Supply: Features 2.5-inch large dials for clear readings. Integrated pressure regulating valve ensures precise control of air compressor input, guaranteeing stable and reliable testing with accurate results
Cylinder Comparison for Confident Diagnostics: Designed for comparative testing. By measuring leakage rates and pressure in problem cylinders vs. healthy cylinders on the same engine, it significantly boosts diagnostic efficiency and reliability
Rugged Construction, Long-Lasting Reliability: Built with industrial-grade materials (premium alloy, shockproof rubber guards). Resists impact, wear, and corrosion – engineered for harsh workshop environments to deliver years of dependable service
